Yes, I know that. My question is, should I respect the behavior
described in the variable's current doc, or the one implemented?
AFAICS, the few modules that use it (ada-mode.el, cc-mode.el,
sgml-mode.el) are doing

   (set (make-local-variable 'comment-line-break-function) whatever)

or equivalent. Does anyone know how does it behave on recent XEmacs?
